Features:
• The rotary motor is from Japan MITSUBISHI MOTORS and the angle decode system is from Germany. They help the goniophotometer rotating smoothly with high accuracy. It is very stable when start and stop.
• The working principles are according to IESNA and CIE. The LSG-2000 completely meets the LM-80, LM-79, LM-75, GB, EN13032-1 and CIE121-1996 standards.
• Special collimation device with laser cross line help you installaing the position of luminaires undertest conveniently and accurately.

Specifications:
• The mirror rotates around the luminaire under test with an angle of (γ) ±180° (or 0-360°) and the luminaire rotates around itself with an angle of (C) ±180° (or 0-360°).
• The accuracy of angle: 0.05°, Resolution of angle: 0.001°
• Accuracy of photo detector: Constant temperature photo detector DIN5032-6/CIE pub1. No. 69 Class L
• LISUN goniophotometer software can export CIE, IES, LDT and other format files. These kinds of format files can be used via other illumination and luminaire design software such as DiaLux.
• Connect goniophotometer to PC via USB cable. English version software can run on Win7, Win8, Win10 Win11.
• LSG-2000 can be used together with a USB CCD Spectrometer to test spatial CCT Distribution and other Spectral color parameters. We call this system “Goniospectroradiometer (LSG-2000CCD)”. Please download the brochure for LSG-2000CCD.
